The globe map occurs as map of the surface of the Earth, which may be manufactured utilizing any of the total of different map projections.

Maps of the globe come typically either 'political' or even 'physical'. A first purpose of a political map is to show territorial borders; the purpose of the physical map is to show features of geography such as mountains, soil type or even land utilize. Geologic maps indicate non exclusively a physical surface, however characteristics of the underlying rock, fault lines, and subsurface structures.

Projections
Maps that depict the surface of the Globe as well utilise a projection, a way of translating a 3-cubic very surface of the geoid to a 2-planar picture. Possibly a right-known globe-map projection is the Mercator Projection, originally designed as a form of nautical chart.

Pilot utilise aeronautic stock and index charts according to the Lambert conformal conic projection, in which a cone is placed on top the division of the gloexist as to be mapped. A cone intersects a sphere (a globe) at one or even deuce parallels which are then chosen when standard lines. This allows the pilots to plot a great-circle route approximatiin on a flat, both-planar chart.
